LAGING-STUD-SETTING MACHINE.

"punch plunger and cutter in the downgpos1t1on illustrating the pawl in, position to engage and rotate thecutter blades uponthe next upward motion of the plunger.

-Fig. -4- 1 is a sectional edge elevation illustrated such. portions of a hook-setting machine as is necessary h to illustrate my present: invention, but my improved mechanism isl'as well adapted for use on aneyeletsetting machine, as the strip serve equally well as a reinforcement for a hook J as for aneyelet, and I hav thereforeadopt edtheterrn lacing stud and have the same throughout 1 the 'specification and claims, whichterm includes both} the hook V and the eyelet.

I-have-herein shown and describedtonly I sufficient mechanism to set forth my present invention.

In thedrawings, 1O designates aportion of the'carriageaframe'in*which is mounted the punch-spindle 11 and the; presserefoot spindle 12, the latter spindle being supported from the frame 10 bytheguide block 13 and also by the collar 14. To this. spindle 11 is 'con'nected the punch 15 which; forms holesin' the upper band also inwthe strip of "stiflened reinforcing tape J 16 for the reception of the lacing studs 17.

Thezcuttervplate 18 is formed preferably in somewhat-0f a star shape, see Fig. 2, comprising a plurality of" radiating arms 20, each having a cutting edge 19 formed at its "outer' end; blades 21, 22 and 23ibeing-of a width to but partially sever the strip, cutting inward from one edge thereof andleaving a narrow uncut portion along theop o- 1 siteedge While the blade 2a isof a width Y7 This cutter plate is rotatably mounted on a: central pivot -25a1wh1ch passes through fit and the downwardly extending supporting plate 26 fixed to the collar 14 best illustrated in Fig. 3.

In order to rotate this cutter blade at the proper time I have provided a springwire pawl 27 fixed at its upper end to the guide-block 13 and arranged to extend down through a hole in the reciprocating collar 14, its end 28 being arranged to engage'the upper edge of the arm which projects outwardly beyond thispawl, whereby as-the plunger rises, the pawl end engages this arm causing the whole plate to rotate and finally the end 28 of the pawl rides outward on the shoulder 29 of the arm, thereby carrying the cutting edge of its arm around parallel with the face of the reinforcing strip ready to cut the same. As the punch plunger descends with its knife blade, it will be seen that the pawl end snaps over the next laterally-extending arm and is then in position to engage this arm which sets in the recess 31 in the plate 26 and is forced by' pressure of the spring 32 into the recess 33 in the back of the knife blade, thereby serving to hold the blade against the friction of the pawl as it is dragged over the cutter arm.

I do not wish to limit myself to the use of a rotating cutter as any style of cutter adapted to partially sever the strip for a predetermined number of times and the completely sever the same, will fall within the spirit and scope of this invention.

The guide-block 34 is connected to the presser foot spindle 12 and is provided with a longitudinal aperture 35 through it which serves as a guide through which the strip 16 passes, and by which the strip is accurately conducted over or to the upper which it is to be laid upon and connected in the desired position thereto by the setting of studs through both.

The outer edge of this block isprovided with a hardened plate 36 having an aperture through which the tape also passes and this plate serves to cooperate with the various edges of the cutter 18, whereby the latter is caused to slide upon that of. the former to sever or partially sever the strip passing through the block.

In the operation of my improved device the tape 16 is led from a roll (not shown) through a suitable guide 37 supported from the arm 38 which is connected to the presser foot 39, see Fig. 1. In this guide I have mounted a tension spring 40 which permits the tape to advance but prevents the same from moving backward during the return stroke of the feeding mechanism. From this guide the tape is led through the aperture in the guide block 34 above the engaging surface of the presser foot and over the cutting edge of the cutter-plate 36.

In setting the machine for the operation of applying a backing strip to the upper 72, the end of the strip is advanced by hand beyond the cutting edge of the block 34 beneath the punch 15. scends piercing the strip and the upper. the

The punch now destrip being partially severed by the blade 18 and then with a lateral motion moves both the strip and upper to the left into the next position over the pocket-plate 41., which latter cooperate with the punch to set and rivet the studs in the upper and at the same time secures the reinforcing strip to I the back thereof. The punch spindle is now raised and moved to the right a distance equal to that between the studs, while-the upper is held in fixed position by the presser foot which in turn holds the partially severed strip riveted thereto. The operation above described is repeated at the setting of each stud, the movement of the head to the left serving to draw out the strip and the setting of the studs secures the strip to the upper to be advanced therewith.

It will be seen from the above description of the knife that each downward stroke of the plunger causes the knife to partially sever the strip and that on the last upward stroke of the plunger before the setting of the last stud into the-upper, the

broadest cutter-plate 24 of the lot is moved into positionvso that this last downward studsetting stroke completely severs this length of strip from the balance thereof, which stroke sets the last stud finally securing the severed length of strip'to this upper. The upper is'now removed from the machine and another positionedtherein and the presser foot lowered to retain the same. y p

The next movement of thisheadin beginning its operation upon the fresh upper is to the right, which causes the strip to extend the desired distance beyond the punch. The next operation forces the spurs or needles l2-into the strip and the punch downward through the projecting end of the strip and the operation of setting the studs in this upper is repeated in the manner above described.

I have shown .and described OIIBQfOIHl of mechanism by which a length of thereinforcing s rip may be severed at intervals and finally completely severed from the main strip, but any mechanism for accomplishing. this function will fall within the spirit and scope of my invention as I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim: 1. In a lacing stud setting machine, means for advancing a reinforcing strip step by step to be attached to the work, a rotatable cutter having a plurality of blades, and means for automatically adjusting said blades to partially sever at intervals and completely sever the strip after a predetermined number of partially severing operations.

52. In a machine of the character described, means for advancing a reinforcing strip to be attached to the work, a rotatable cutter having a plurality of blades for partially severing the strip at intervals and com pletely severing the strip after a predetermined number of partially severing operations, a pawl for engaging and automatically rotating said cutter after each cut ting operation, and means for preventing a retrograde motion of the cutter after having been advanced by said pawl.

3. In a lacing stud setting machine, feed ing means for simultaneously advancing the work and a reinforcing strip step by step to receive a stud through both, a pivotally mounted rotatable cutter having blades of different widths for partially severing the strip at intervals, a spring pawl for rotating said blades to present a fresh one after each cutting operation and finally presenting a wide blade for completely severing the strip after a predetermined number of partially severing operations.

In testimony whereof I aflix my signature in presence of a witness.
